I was on my way to the states from Germany. I was 8 1/2 months pregnant, with a 10 month old. The man in front of me put his seat all the way back which touched my belly. I am the last person to call attention to myself, so I just dealt with it, until I had to go to the bathroom. I asked him to raise his seat, and told him why. He refused to do so, so unlike me, I said in a raised voice, "If you don't let me out, I will pee on you" He sat up, and the man across helped me get up. Since it is a 10 hour flight, I because the entertainment.
From then on, when I showed discomfort, everyone said "she's got to pee"
Two men fighting on a plane, would scare me to death. It is so small an area to fight, and you never know when they might do something else.
